Tidy SPARQL Query

tidy_sparql.Rd

Tidies SPARQL query results according to desired specifications (see tidy_what parameter for details).

Usage

tidy_sparql(query_res, tidy_what = "everything", ...)

Arguments

query_res

The results of a SPARQL query, as a data.frame (usually produced by owl_xml()$query() or similar from DOrepo(), but can also be used to tidy results of robot("query", ...) loaded with readr).

tidy_what

The elements of a SPARQL-created data.frame to tidy, as a character vector. One or more of the following:

  • "everything" to apply all tidy operations (has precedence over "nothing").

  • "header" to remove leading ? from header labels.

  • "unnest" to unnest list columns with unnest_cross().

  • "uri_to_curie" to convert all URIs recognized by DO.utils to CURIEs with to_curie().

  • "lgl_NA_FALSE" to replace NA in logical columns with FALSE.

  • "as_tibble" to make the output a tibble.

  • "rm_lang_tag" to remove language tags. Tags will only be removed from character class columns, and then only if there is one unique language tag in the given column.

  • "nothing" to prevent all tidying.

...

Arguments passed on to to_curie

strip_angle_brackets

Whether to remove all < and > from the input, as a boolean (default: TRUE). Where this might have undesirable consequences, e.g. some angle brackets need to be removed, perform the removal beforehand and use strip_angle_brackets = FALSE.
